Attention is called to the fact that both ends of the reservoirs are curved to conform to the configuration of the brush head illustrated, thus improving the esthetic appearance of the attachment and rigidifying the same against collapse. Each of the reservoirs are further reinforced by indentations 42 in the outer walls 26 whose bottoms 44 abut against the inner walls 25 to aid in maintaining the two walls in proper spaced relationship.

The top of each reservoir is closed off by a wall 46 securely fixed to the inner and outer walls 26, 28. At spaced points along this wall through openings 48 are provided from which stub outlets 56 depend. Conduits 52 attached to said outlets serve as the means for slowly conducting pairzit, caught on the wall 46, to the reservoirs 22, 4.

In accordance with the invention these con duits, which may be made from any form-maintaining material such as rubber, plastic or the like, have a diameter small enough to impede the flow of paint therethrough. The conduits are not small enough to act as capillary tubes and thus prevent the flow of paint, nor are they so large that they allow paint to run rapidly therethrough. I have found that a suitable conduit diameter is in the neighborhood of three-sixteenths of an inch. In order to have the conduits large enough for ready cleaning and yet not let the paint run through the same too quick 1y, their length may be increased by helically convoluting the same as shown. In this manner the friction head of the conduits, which impedes passage of the paint therethrough, has a large value per unit length measured along the axis of the helix. The convolutions may extend from the top Wall 46 to bottom wall 30 and when oc cupying such a position act as a highly efficient trap which prevents paint from flowing back to the bristles from the reservoir when the handle is higher than the brushhead. To further increase the overall friction head the flow of adjacent conduits may be paired, that is, the con.. voluted conduits running from adjacent openings 48 may each have one end connected to a stub outlet 56 and the other end to a branch of a Y- fitting 54 to whose trunk there is secured another conduit 56 whose lower free end is disposed near the bottom wall 30. The overall length of these conduits 52, 56 is suflicient to ensure that paint will flow but slowly therethrough. As a matter or fact this length is great enough to prevent the rapid flow therethrough of even thin, relatively watery, coating fluids such as whitewash or shingle paint. Where enamels are to be regularly used the conduits may be made shorter, less convoluted or of a larger diameter.

. Paint which accumulates in the reservoir may be drained therefrom by manipulation of a valve 51 (Fig. 9) in each reservoir. Said valves, which are of extremely simple construction, each comprises an orifice 58 in the bottom wall 36 which is normally closed by a tapered valve plug 66 urged against said wall by a spring 62 which is held under compression between the top of the plug and a washer 64 in the reservoir. Said washer'lies under a tube 66 which encircles the operating spindle 68 for the valve,-the upper end of said tube bearing against packing 16 below the top wall 46 of the reservoir. The valve spindle passes through said top wall and is bent over to provide a manipulating handle 12 which is received in a notch 14 of a wall 16, shortly to be described. Said notch has a bayonet slot 18 which prevents the handle from being accidentally moved to open the valve.

Both the inner and outer walls 26, 28 of the reservoirs 22, 24 are continued above the top walls 46. The extension of the inner wall 26 is a flange 86 which is inclined towards the bristles l6 and is adapted to have its upper edge firmly engaged against said bristles so that any paint which runs down toward the handle l2 will flow over said flange to the top of the wall 46 where it is caught and will gravitate through the openings 48 and conduits 52, 56 into the reservoirs 22,

To expedite the formation of a tight grip between the flanges 86 and bristle l6 the upper edges of said flanges may be serrated as at 82 (Fig. l), this construction enabling said edges to better place the bristles under compression and to compensate for any deviations of said edges from rectilinearity.

Flow of paint into the conduits 52 may also be facilitated by providing high spots 64 between the openings 48 and sloping the wall from said high spots to theopenings (Fig. 1)

There is a tendency for paint to leak through the junction of the flanges where the end of the reservoir 22, 24' abut. I prevent this by specially constructing the ends of the flanges in the following manner. Each end of the flange associated with one reservoir-22 is provided with an integral inset tongue 86 which is adapted when the attachment 20 is secured to the brush to 'be captively received in a channel in the matching end of the flange associated with the other reservoir 24. The channel is formed by securing a Z-strip 88 to the inside of the wall 26.

Said inset tongues and Zstrips are continued under the ends of the walls 46, to effect a painttight joint of the walls 46 at both ends of the reservoirs.

edge 96 is curled in to permit the paint brush to be substantially tilted, with the head above the handle, without allowing liquid paint accumulated in the trough 92 to run out. Said trough is defined by the wall .46 and the flanges I6, 86. Leakage of paint through the juncture of the flanges 16 is prevented by resilient strips 93.

It will be noted that the inner walls 26 :are

spaced slightly fromthe brush end I4: and ferrule l8. However, the attachment 20 must grip the brush firmly atpoints other than thezbristles. For this purpose I provide a plurality of almost vertically disposed, horizontally extending leaf springs 94, 96 on the inner face of'the attachment, one edge of said springs being secured to the inner walls 26 and the other edge,- when the attachment is closed, frictionally engaging the ferrule 18. The upper spring 94has itslower edge pressed against said ferrule and the lower spring 96 its upper edge pressed against'the ferrule thereby securing a'balanced frictional connection' between the attachment 26 and paint brush handle on both halves of said attachment.

Additional means may also be provided to aid in preventing shifting of; the attachment on the paint brush, said means comprising a clip 98 secured to the bottom wall 36 of each of the reservoirs. Each clip has two inturned fingers I00 which are adapted to flatly press against the bottom of the brush head l4.

It may be mentioned thatpalthough Ihave shown the two reservoirs -as having oppositely facing internally convex shapes, said reservoirs may be joined by eliminating the end walls 32, 3.4 adjacent the hinge and substituting a flexible oonnectionof leather, rubber or-the like between the matchin ends of the walls 28,23 or by interconnecting said reservoirs with a conduit.

To place the attachment on the brush, one

reservoir is fitted in proper position on the ferrule and the two halves of theconduit pivoted about the hinge so as to force the two open ends of the reservoirs into contact. The attachment is held in place by locking the bail 38 on the catch 48. For painting, the bristles of the brush are dippedinpaint in the customary manner and the brush wielded as-usual to paint a surface. the handle 12, paint will run down "the bristles on to the outer surfaces of the flange 88 and thence on to the top wall 46 where it is caught in the trough 92. From the trough the paint will flow through the conduits 52, 56 into the reservoir. The conduits will pass the paint sufficiently rapidly to prevent any paint-from overflowing the lip 96 of the outer flange 76. Once the paint has entered into the reservoirs 22, 24 it is trapped there, since when the bristles of the brush are above the handle l2 paint can only gravitate into the reservoir and when the handle 12 is above the bristles the open ends of the conduits 55 are above the level of the paint in the reservoir.

It may sometimes be desirable to permit the paint which is trapped in the reservoirs to flow slowly back into the bristles when the handle is above the brush head l4. To this end I may modify the foregoing construction in the manner shown in Fig. 11 by providing a set of conduits 52', 55' the free ends 55a of which are relatively close to the top wall 56. With this construction, after a certain amount of paint has accumulated in the reservoirs and the handle I2 is raised above the bristles, paint will flow from the reservoirs back into the bristles. The convoluted conduits will retard the flow of paint to such an extent that the paint will not rush rapidly from the reservoir into the bristles too fast to prevent efficient painting. If desired, the reservoirs may be charged with paint through the valve orifices 58 so as to provide a steady flow of paint to the bristles even though the bristles are never raised above the level of the handle.

I may improve the grip effected between the halves of the attachment 28 and the paint brush by covering the brush head and ferrule with a sheath I82 of a flexible resilient material such as rubber. This sheath will cling to the brush head and ferrule obtaining good frictional contact with said brush head and ferrule on one side and with the springs 9d, 96 and fingers Hill on the other side. Said sheath also functions to preserve the ferrule and brush end of the handle by protecting the same from water even when the attachment 2%! is removed.

It will thus be seen that there is provided a device which achieves the several objects of this invention and which is well adapted to meet all conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiments above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings Each time the bristles are raised above is;to .be interpreted as illustrative and n t in a limiting sense.

Having thus described. my invention, I claim as newand desire to-secureby LettersPatent:
